US and Iran claim a path to keep Hormuz open—while allies question Washington’s deal-making

On June 22, 2026, US Vice President JD Vance said the US and Iran had found a way to keep the Strait of Hormuz open, noting that roughly 15 million barrels of oil had already been transported via the waterway. The same day, US Secretary of State Marco Rubio traveled to the United Arab Emirates, Kuwait, and Bahrain to address doubts about the US-Iran pact, underscoring that Gulf partners are not fully aligned with Washington’s narrative. France24 framed the emerging US-Iran “peace deal” as far narrower than the expansive, detailed Obama-era agreement, while political analysts highlighted how US domestic politics and threat rhetoric shape negotiating leverage. Separately, Foreign Policy argued that US strategy risks “farcepolitik,” and the Financial Times reported that America’s allies are increasingly considering economic independence from the US. Geopolitically, the core contest is whether Washington can convert a tactical de-risking of Hormuz into a durable regional security architecture without losing credibility with key Gulf stakeholders. If the Strait remains open, the immediate beneficiary is global oil trade and any US-led effort to prevent a maritime supply shock; however, the need for Rubio’s trip signals persistent trust deficits with the UAE, Kuwait, and Bahrain. The comparison to the Obama framework implies that the current approach may trade breadth for speed, potentially leaving enforcement, verification, or regional spillovers less clearly bounded. Meanwhile, the FT’s “allies independence” theme suggests a broader power-diffusion dynamic: even partners who benefit from US security guarantees may hedge economically if they perceive US commitments as volatile. Market implications center on energy risk premia, shipping insurance, and crude benchmarks sensitive to Hormuz disruption. The claim of 15 million barrels already moving through the Strait is a near-term reassurance that can reduce tail-risk pricing in Brent and WTI, but it does not eliminate the probability of sudden escalation given the emphasis on threats and negotiation posture. Gulf uncertainty can also affect regional refining and petrochemical feedstock flows, with potential knock-ons to Middle East crude differentials and freight rates for tankers transiting the Persian Gulf. If allies accelerate economic decoupling, the longer-term market effect could be a gradual shift in trade and investment patterns, influencing currency and capital flows tied to US dollar invoicing and regional hedging behavior. What to watch next is whether Rubio’s consultations in the UAE, Kuwait, and Bahrain produce concrete assurances on enforcement mechanisms, maritime safety arrangements, and any carve-outs for regional actors. The next trigger is the pace and content of US-Iran negotiations: analysts’ skepticism that this deal will not match the Obama agreement raises the risk of gaps that could reintroduce escalation incentives. On the market side, monitor tanker traffic, insurance spreads, and crude volatility around Hormuz, especially any signals that throughput is slowing or rerouting. A de-escalation path would be sustained statements paired with operational evidence of continued safe passage, while escalation would be indicated by renewed hardline rhetoric, maritime incidents, or partner governments publicly distancing themselves from Washington’s pact.

Geopolitical Implications

• 01

  Credibility test for Washington with Gulf security and energy stakeholders.

• 02

  Potential enforcement and verification gaps versus the Obama-era framework.

• 03

  Domestic US threat rhetoric may constrain bargaining and raise volatility.

• 04

  Allies’ economic hedging could reduce US leverage over time.
